Some weird glitch... O.o

Ok, so when I was trying to create a thread in announcements, I clicked "submit". But then a really weird thingy happened. It didn't say "Click here to view your message" or something. So when it redirected me back to the main page, it just showed my name in the last post link box. There wasn't an arrow or a piece or paper, linking to the last post. Is this a glitch? Because this happens every time when I go to the admin panel and update the forum.
